IMPROVEMENT IN COTTON-GINS.

Specification forming part of Letters Patent No. 133,080, dated November 19, 1872.`

To all whom it may concern: v

Be it known that I, JEFFERSON M. GLOUGH, of Ilion, in the county of Herkimer and State of New York, have invented certain Improvements in Ginning and Burrin g Machinery; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in which- Figure l, Plate l, is an elevation of one side of the machine; Fig. 2, Plate 1, is a section taken vertically and longitudinally through the center of the machine; Fig. 3, Plate 2, is a 'ont view of the ginning-cylinder and ribbed drum; and Fig. 4, Plate 3, is a diametrical section through the ginning-cylinder.

Similar letters of reference indicate corresponding parts in the several gures.

This invention relates to improvements on machinery for ginning cotton and burringwool, wherein I employ a cylinder the periphery of which is composed of teeth and ribs alternating with one another, as will be hereinafter explained. Prior to my'invention devices for stirring the stock prior to its subjection to the ginning-cylinder have been employed; but by the contrivance hereinafter explained I can dispense altogether with such separate stirring devices and construct the ginning cylinder so that it will do the whole work without materially increasing the power required to operate the machine.

The following description will enable others skilled in the art to understand my invention.

In the accompanying drawing, A A represent the close sides ofthe frame; B C, the hinged covers; t t, transverse braces; C, the discharge-spout; and C', its adjustable bottom. At the front end of the machine is arranged a Ahorizontal and transverse ginningcylinder, which will be hereinafter described, and in front of this cylinder are adjustable gates m m, by which the size of the feedopening is regulated. Above the cylinder and a little in rea-r of a plane passing vertically through its axis is a ribbed drum, D, over which is a fixed clearer, d, and over and behind whieh is an apron, d', as shown in Fig. 1. In rear of the cylinder G are the rotary stripping-brushes b, which are secured to heads J on a shaft, e. On one end of the shaft e a belt-pulley, e', is keyed, over which a belt is passed that leads from a large drum, G',

on the shaft g of cylinder G. The belt c is stretched around a loose pulley, d, which has its bearing on a stud that is secured to the side A of the frame. By the arrangement of the belt c, as shown in Fig. l, the strippingbrushes b rotate in an opposite direction to the rotation of the ginning-cylinder G. By means of a spur-wheel, g1, on the ginning-cylinder shaft g, a pinion, g3, on the shaft of theribbed drum D, and an intermediate spurwheel, g2, rotary motion is given to said ribbed drum. The ginning-cylinder G, which may be made hollow for the purpose of securing lightness, presents ribs 1 and teeth s on its surface, arranged alternately with narrow spaces between them, as shown in Figs. 3 and 4. These teeth, as well as the ribs,.are continuous from one end to the other of the cylinder, and in their spiral turns around the cylinder they are given a serpentine orwaved course, as shown in Fig. 3. The ribs 1' are formed on the cylinder, but the teeth s are inserted into it. This is done as follows: The teeth are formed on narrow strips, which, in cross-section, are of a wedge form or dovetailed, and are forced endwise into a dovetail groove which winds around the cylinder between the ribs in the serpentine manner stated. After the strips of teeth are inserted into theirV places they are keyed up fast and the cylinder is complete.

It will be seen, from the above description of my ginning-cylinder, that the serpentine arrangement of the teeth give a lateral shaking or stirring motion to the stock, thus loosening it and keeping it loose on the face of the cylinder, preventing it roping and allowing the teeth to get hold of the fibers readily, which adds to quantity as well as quality.

By my invention I stir at the right time and right place, and as the teeth are in zigzag or serpentine grooves, they hunt after the fibers at the working-point, and do not form a chanriel in them, as a regular spiral or circle would Having described my invention, I claim as new and desire to secure by Letters Patent- 1. A ginning or burring cylinder which has teeth inserted into it in a serpentine manner7 composed of teeth arranged around it in a sersubstantially as described. pentine manner with the strippers b, snbstan 2.
